Ameobi silences Owls
The 27-year-old scored for the fourth time in five days after his hat-trick against Reading to put his club level on points with leaders Cardiff and second-placed Middlesbrough and marginally behind on goal difference.
Ameobi struck in front of a crowd of 43,904 after just 15 minutes, although Newcastle were unable to find a second goal and it took good saves by Steve Harper from former Sunderland full-back Michael Gray and substitute Francis Jeffers to ensure all three points stayed on Tyneside.
